Niles ABS-1 Signal Activated Speaker Level A-B Switch NEW IN SEALED BOX

Here's the scenario: You've already wired your house with remote speakers in different rooms, all being driven by your main receiver. There's a separate audio system in your bedroom, and you'd like to use its amplifier to play the audio through the same speakers you've got wired to your multi-room system. But how do you wire two amplifiers to the same set of speakers without damaging your equipment?The Niles ABS-1 solves that problem. It provides safe switching between two amplifiers — like the one in your main system and the one in your bedroom — and a single pair of speakers. Operation is automatic: when the ABS-1 senses a signal from your secondary amp, it passes it on to the speakers. The speakers in the rest of the house are unaffected, so your main system continues to play elsewhere.Now, back to our scenario: Install the ABS-1, and when you want to listen to your smaller system through your bedroom speakers, just turn it on and the ABS-1 does the rest.Details:speaker-level i Perfect for everyday use. High quality materials and excellent craftsmanship ensure long-lasting durability.
